Modify /reservation/demo.php to validate and sanitize user input
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection attempts
Add WAF rule: deny requests with SQL keywords in 'Start' parameter
🧯 If You Can't Patch
- Remove or restrict access to /reservation/demo.php file
- Implement network segmentation to isolate the vulnerable system
🔍 How to Verify
Check if Vulnerable:
Test if /reservation/demo.php accepts SQL injection payloads in the 'Start' parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and input is properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts from single IP
- Requests to /reservation/demo.php with SQL keywords
Network Indicators:
- Unusual database connection patterns
- HTTP requests containing SQL injection payloads
SIEM Query:
source="web_logs" AND uri="/reservation/demo.php" AND (query CONTAINS "UNION" OR query CONTAINS "SELECT" OR query CONTAINS "INSERT")
